WINDMILL-OILER.

Specification of Letters Patent.

Patented Ju1y'13, 1969.

Application filed M1931, 1908. Serial No. 446,228.

To all whom it may concern:

Be it known that I, HARVEY A. MowREY, a citizen of the United States, residing at Valley Falls, in the county of Jefferson and State of Kansas, have invented a new and useful Improvement in Windmill-Oilers, of which the following is a specification.

My invention relates to automatic or semiautomatic devices for oiling the bearings of windmills; the object being to provide a device whereby a person on the ground may, by simple operation supply the various bearings with a given amount of oil, the amount for each bearing being measured, so that each bearing will receive its proper portion of the oil. And my invention consists of a container adapted to hold a quantity of oil and to be aflixed to the upper works of the win dmill and provided with a series of varioussized cylinders or tubes, with pistons, whereby a measured quantity of oil may be discharged through the respective cylinders, said pistons being operated by a cord which extends down through the wind mill head and center bearing, to the ground where it may be operated by the person whenever he desires to oil the Windmill.

It also consists of the parts, improvements, and combinations herein set forth and claimed.

In the drawings accompanying and forming part of this specificatlon, and in the description of the drawings, I have shown my invention in its preferred form, and have shown the best mode of applying the principles thereof; but it is to be understood that my invention is not confined to the exact details of these drawings and of that description, and that I contemplate changes in form, proportions, and materials, the transposition of parts, and the substitution of equivalent members, within the scope of the appended claim, without departing from the spirit of the invention.

Figure 1 is a plan view of an oiler made in accordance with the principles of my invention, the cover being removed; and Fig. 2 is a vertical center sectional view of the same.

Similar reference characters indicate like or corresponding parts throughout the several views.

1 is a suitable oil container, as a tin or galvanized iron can, large enough to hold a suitable quantity of oil, say a gallon and a half or two gallons; 2 is a removable cover, and 3 is the bottom.

.tom of the container. each tube or cylinder are slightly flared out- 4, 5, 6, 7, 8, and 9 are a series of cylinders, or tubes, arranged in a circle in the bottom of the can or tank, and of varying diameters, their upper ends being secured to the inner or false bottom 10, which forms the inside bot- The ends 11, 11 of wardly; and 12 is an enlarged continuation of each tube or cylinder, while 13 is a leading therefrom to conduct the oil to'any desired place or be aring. In each cylinder work two pistons, each of which may be, in simple form, a leather washer 14, held in place on the threaded lower end 16 of a rod- 17, ahd between the two j am-nuts 15, 15, and so spaced apart on the rod that when the rod is down, the lower washer will be below the flared end, thereby permitting the oil between the two washers to flow out into 12 and 13, and when the rod is up the lower washer may occupy the position in which the upper washer is shown in the drawings, the upper washer being then correspondingly elevated; whereby, by the operation of the rod u and down, the cylinder will be filled and ischarged, thus discharging only a measured amount witlr each downward operation. The object in having several sizes of these cylinders is to give each bearing just the comparative amount of oil which it should have, instead of giving them all an equal amount, as some bearings require more oil than others. 01' course, the arrangement of the cylinders in the drawings is somewhat arbitrary, it being the intent of my invention that these may be varied to suit any circumstance. Thus, the sizes may be greater or smaller, or there may be more than one of the same size, or there may be more than one conducting pipe leading from each or any of the cylinders.

All of the rods 17, 17 are connected to a spider or frame 18, which is in turn secured to a rod 19, which extends down through a tube 20 and through the bottom of the can, where it may be connected to a cord 21. Within the tube is a compression spring 22 which bears between the bottom and. the ring or collar 23 on the rod 19, thus tending normally to hold the rod and the valves or pistons in their upper positions, with the nut 24 against the under side of the can. On pulling the cord 21, the valves or pistons will be operated together, to effect their several dis charges of oil, as above indicated.

If it be desired to remove the valves, the cord and nut 24 may be removed, and the entire assembly of rods, s ider, and pistons may be taken out through t e top of the can; they may be aseasily put back again, by the re verse operation. 1 1

Preferably,the tank is mounted on top of the Windmill head, With the several conducting tubes leading off to the several bearings,

While the cord may be extendedflown through I the same center hollow bearing through which the other controlling cords and rods of the Windmill are extended. A sufficient quantity of oil may first be laced in the can for supplying the windmill 'or a long period, say forseveral months, and by pulling the cord, the operator may be assured that the roper supply of oil Will be given to each bearing connectedwith the can. This cord may be pulled as often as needed; and When the Windmill is not in continuous operation there Will be no Waste of oil, thefeed being entirely Within the control of the. operator on the ground.

, What I claim is: I

In a device ofthe kind described, the combination of an oil container, a series of cylinders of various sizes arrangedin the bottom thereof, a pair of pistons Working in each cylinden and a stem connecting same so that res ective pistons; allsubstantially as shown.

n testimony whereof, I have hereunto signed my name 1n the presence of subscribing Witnesses.
